Have you tried using the Intel driver at Download Network Adapter Driver for Windows® 10. We recommend customer to use the OEM driver from the board vendor for onboard NIC. since you already tried the driver from SuperMicro, you might want to give this a try.
Please make sure the switch you are connecting has the same speed setting and autonegotiation mode.
You can further check with Supermicro* as this is an onboard NIC.
Thank you for the reply. I have already installed the link you provided and am currently using the following:
Intel PROSet Version: 18.104.22.168
Driver Version: 22.214.171.124
Driver Date: 5/4/2015
I notice the driver version is many months older than the date provided on the download page (10/02/2015). Do you know if the latest driver was successfully installed or is the driver version I'm using still quite old?
Both switch and adapter are in auto negotiation mode. For some reason I have a hunch the issue is related to congestion control so I'm going to research that path a bit further as well.
Thank you for the update. The date provided on the download page dated 10/2/2015 refers to the PROSet software, the driver contained in the PROset software can be older since only some changes made in the software. Please refer to what is new in the Release notes https://downloadmirror.intel.com/25016/eng/readme.txt.
